- Page 22 The two PV string inputs operate independently, and each has an independent MPPT. Therefore, the two photovoltaic inputs can be different from each other, including: different panel types; different numbers of cells in the PV string; different inclination angles, different azimuth angles. NOTE In order to make full use of the DC input power, the PV strings of the same input should be close to the same (especially the voltage), including: the same model;...
- Page 23 1. This series of connectors only supports multi-strand copper wires. Cut and strip as required, the stripping length is 7-8mm. 2. Crimp the wire. Place the terminal correctly in the terminal crimping pliers, then put the bare copper wire part of the cable into the terminal opening slot and press it firmly. Be careful not to damage the terminals and the copper wires of the wires.
- Page 24 WARNING When wiring the PV cable, the positive and negative poles must be connected correctly. Please cut off the power of the system and verify whether the male and female connectors are of the same model before use. 4. After the cable is plugged in, use a special wrench or adjustable wrench to tighten the nut. In order to achieve better results, two wrenches can be used to work together.
- Page 25 ● Grounding WARNING Since the inverter is a transformerless type, it is required that the positive and negative poles of the photovoltaic string cannot be grounded, otherwise the inverter will not operate normally. Grounding system In this PV power generation system, all non-current-carrying metal parts and equipment housings should be grounded (such as the bracket of the PV arrays, the inverter housing, etc.).
